城市生命线地震后恢复曲线与恢复过程优化的影响因素分析

恢复曲线的研究是城市生命线恢复过程和震灾的重要手段，它揭示恢复率与震后时间的关系，文中探讨了恢复曲线图的构造及相关参数的物理意义，恢复过程优化的数学模型及影响优化的主要因素（震后开始恢复时间ｔｆ、每一恢复单元的恢复时间ｔｉ、恢复单元数与恢复顺序等）的分析。

Analysis on the factors affecting post-quake urban lifeline recovery curve and recovery course optimization

The research of recovery curve is important for post-quake urban lifeline recovery and disaster mitigati on. The curve reflects the relationship between recovery ratio and time period after earthquake. The establishment of recovery curve diagram and physical sens e of its correlated parameters are discussed. The digital model for recovery co urse optimization and the factors affecting recovery course optimization (starti ng time of post-quake recovery tf, recovery time of every recovery unit ti, the number of recovery units, and recovery sequence) are analyzed.
